The following table shows a map of the actual and proposed allocation on Plane 2, the
SIP (Supplementary Ideographic Plane). A
description of the presentation conventions used in the table is at
the bottom of this page. The SIP is intended for encoding of additional repertoire of Unified CJK ideographs or Compatibility CJK ideographs. Other CJK related characters, including strokes, radicals, and punctuation are encoded on the BMP.
This document is informative and those parts reflecting proposals are of a provisional nature. Please send corrigenda and other comments to the authors using the online contact form.
Plane 2 is tentatively mapped out to the following zones.
00020000-0002A6DF CJK Unified Ideographs Extension B
0002A700-0002B73F CJK Unified Ideographs Extension C
0002B740-0002B81F CJK Unified Ideographs Extension D
0002B820-0002F7FF CJK Unified Ideographs Extension E
0002F800-0002FA1F CJK Compatibility Ideographs Supplement
NOTE: Should Plane 2, the SIP (Supplementary Ideographic Plane) prove insufficient for future Han character encoding, it is anticipated that further allocations may be provided on Plane 3.

??? in a block indicates that no
suggestion has been made regarding the block allocation.
Color highlighting is used to indicate blocks
and unassigned ranges which default to right-to-left character
Grey shading is used to indicate ranges of
control characters and noncharacters.
NOTE: When scripts are actually proposed to the UTC or to WG2,
the practice is to "front" them in the zones to which they are
tentatively allocated, and to adjust the block size with regard to
the allocation proposed.
The size and location of the unallocated script blocks are merely
proposals based on the current state of planning. The size and
location of a script may change during final allocation of the
